In my ferver to own an e51, I accidentally purchased the European model, rather than U.S. model. I have called tech support, and am told that the software on the European vs. U.S. models are different. I am unable to connect the phone to our phone system using SIP. Other phones and softphones work wonderfully, but not my e51. I am wondering if a simple misunderstanding of the terms used in setup is the culprit. For example, in the U.S. we don't use the term "Realm", so I don't know what information to put in this field.
Also, I'm wondering if the SIP configuration is the same on the U.S. model as the European model phone.
Any help will be greatly appreciated.
Thank you in advance.
